Tool
Fill Out PDF
Complete PDF forms on screen by typing into the fields, ticking the boxes and choosing from the lists. Save it to keep it editable, or flatten it so the answers can’t be changed.

How to fill out PDF
- Choose or drop the PDF form.
- Click into each field and fill it in. Tab moves to the next one.
- Choose whether to lock the answers, then select “Save filled PDF”.
Private by design
Most online PDF tools upload your document to their servers. This one doesn’t: Fill Out PDF runs entirely in your browser, so contracts, forms, IDs and photos never leave your device. It’s free and adds no watermark, and you don’t need an account.
Questions
My PDF has lines to write on but no fields. What now?
It's a flat form. Use Edit PDF to type text onto the lines, or Create Fillable PDF to add real fields first.
What does “Lock answers” do?
It flattens the form, turning your answers into ordinary page content so nobody can change them. Keep it off if you or someone else will need to edit the answers.
Does it support XFA forms?
No. XFA is an older Adobe format that only Acrobat fully supports. Most government and business forms use standard fields, which work here.
Are my files uploaded?
No. Every tool runs in your web browser, so your files are read, changed and saved on your own device and never sent to LabAnvil or anyone else. Once the page has loaded, the tools even work offline.
Is it free? Do I need an account?
Free, with no watermark, no daily limit and no account.
